ryroenarmoan MACHINE;

Application filed May 7,

This invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaler, wherein circulating matrices are'releascd from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type 5 characters thereon, and the matricesthereafter elevated and re turned through distributing mechanism to the magazine from which they started. More particularly, it relates to that class of linotypeimachines equipped with a plurality of magazines mountedin or carried by a so-called shift-frame, which is movable upwardly. and downwardly in the machine frame to bring one or another of the magazines into operative relationto the assembling and distributing devices. Inthe commercial machines of this type, the shifting of the magazines is accomplished by means of screw mechanism operated by a hand crankconveniently located at the front of the machine. While this arrangement is thoroughly practical, the operation has always been slow and tedious and more or less laborious.

The present: invention contemplates the use of. powerfor raising and lowering the magazines, and; the mechanism herein provided presents many advantages over prior devices, besides being readily applicable to In the preferred embodiment illustrated, the inelined lay shaft, ordinarily employed. for turning the magazine elevating screw, is operat-ively connected to compact, reversible gear mechanism driven by the well-known intermediate shaft and controlled directly from the front of themachine by means of a clutch shifting rod rotatably mounted in the fore-and-aft assembler drive shaft. Moreover, the customary bevel gears used for driving the said assembler shaft serve as constituents of the proposed mechanism, thereby simplifying the construction and reducing the cost of manufacture.

In the accompanying drawings, the inven- 1927. Serial No. 189,509.

tion has been shown merely in preferred form and by way of example, and obviously many changes and variations may be made therein and in its mode of adaptation which willstill be comprised within its spirit. It is to be understood, therefore, that thein-- vention is not limited to any specific form or embodiment except in so far as such limitations are specified in the claims.

Referring to thedrawings; Fig. 1 is a side elevation of a portion of a linotype machine equipped with the pres 1 ent] improvements; p

The several magazines A are mountedupon the separate base frames A conjointly constituting a shift frame which is arranged to be moved upwardlyand down wardly in the fixed machine frame to bring any selected oneof the magazines into operatlve relation-to the assembler entrance B and the magazine entranceC, the latter 1ead 111g from the distributor D and servingto conduct the matrices to their proper maga-. zine channels. The release of thefmatrices from the. operativeunagazine is controlled in the usual, way from the keyboard E through the medium of reeds and levers not shown. The magazine shift frame (Fig. 1) iscarried by the sliding plungerA. which. is mounted in the sleeve 0 secured rigidly to the main framepand which engages the screw F geared at its lower end to the inclined layshaft F the arrangement beingsuch that the rotation of saidfshaft in onedirection or the other turns the screw in a corresponding direction and causes it to raise or lower the shift frame. At its for ward; end, the lay shaftF (see Fig. 2) is provided with the horizontal extension F supported in suitable bearings secured to the intermediate bracket O Also supported in suitable bearings of the intermediate bracket O is the fore-and-aft assembler drive shaft Gr, common to all machines of the present type, and which is arranged above and in close proximity to the keyboard E. This,

seated in the fork K and engaging .a corresponding recess. formed in the pivot pin K may be employed to maintain the clutch member yieldingly in suchdisengaged or nentralposition. By throwing the handle K to the right, the collar or crank K will shift the clutch member K toward the gear H and, as the friction clutch surface lc engages the opposing clutch surface 7t,a driving connection will i be established be tween the intermediate shaftH and the lay shaft FF through the medium of the foreand-aft pulley shaft gear G this Connection causingthe lay shaft to be turned in one direction to. lower the magazine shift frame. Conversely, iwhen the control handle is thrown to the left, the jaw'clntch member 7:?is brought into engagement with the coo )eratin clu-tc hinember. [L of the reversin t: c

gear H and the driving connection thus stablishedcauses the lay shaft to be driven directly by theintermediate shaft Hin the opposite direction to raise the magazine shift frame. As a precaution against dam age that might be caused by some obstruction in the path oft-he magazines or other moving parts when the jaw clutch surfaces are engaged, it is proposed to, incorporate in the driving connections some sort of slip joint oryeouplingF, such as that indicated in Fig. l and as applied tothe inclined portion of the lay shaft F v 1 y The operation of the: parts will now be clear; Assumingthe upper magazine tobe in operative position and tha t one. of the lower. magazines is selectedfor use, pressure is first applied with one hand to the lever J" which controls the movement the gauge bars J, J 1 and, with the other hand, the control handle K is rocked to the left to engage the positive clutch members 71, and 7c to elevate the magazines As the magazines start to move up, the. gauge bars are freed from the weight of the magazine structure and continued hand pressure on the lever; J withdrawsthem to their inactive position out of the path of the lugs A". Then the magazine selected has reached apoint slight ly above its normal operative position, the lever J isreleased and the actuating springs j draw the gauge bars back to theiractive position with their upper ends beneath the aligning lugs of said magazine. The coin trol handleflK? is now rocked to the right to engage the friction clutch surfaces It and 1 6 to lower the magazines until the aligning lugs A of the selected magazine settle down upon the tops of the gauge bars J, J at which time the control handle is returnedto its central position to place the clutch member K in neutral. As the magazines are thus lowered, the friction clutch surfaces h, k serve, by the slippage which they permit, to prevent any damage to or any unnecessary strain upontheparts When a changeof magazines necessitates a lowering of the magazines, the latter must first be raised slightly in thema'nner jnststated, to free the gauge bars J, J preparatory to their withdrawal. The operation of the control handle is then reversed to engage the fric tion clutch surfaces h, M which should be held in. engagement until the desired iii-agazine is arrested by the gaugebars, the latter meanwhile havingbeen released in time to rcsun'ie their normal position for engaga ment with'the aligning lugs A f of the magazinc selected.
